c# 长行代码格式化

Question

这行代码是我写的。这是不可读的。有没有巧妙的方法将其分解为多行代码 < 80 或 100 个字符长度？

Console.WriteLine(String.Join("\n", testResults.Select(row => String.Join("|", row.Select(column => String.Format("{0,20 }", column.ToString())))));

我建议将query 本身和它的最终表示(控制台输出)分开:

// Query: what to output
var testReport = testResults
  .Select(row => String.Join("|", row
     .Select(column => String.Format("{0,20}", column)))); // .ToString() is redundant

// Representation: how to output (print on the console in one go)
Console.WriteLine(String.Join(Environment.NewLine, testReport));
